Why Use Our My IP History Tool?
Instant IP Detection
Check your current public IP address instantly using the ipify.org API. Your IP is fetched directly from your browser with automatic detection and no manual input required - just click "Check Now" to record your current IP.
IP Change History Tracking
Every time your public IP changes, the tool automatically records the new IP along with a timestamp. View a complete timeline of IP transitions, see when each IP was first detected, and track how long each IP was active.
Detailed Analytics & Statistics
Get instant insights into your IP stability with detailed statistics: total number of unique IPs recorded, days tracked, IP change frequency, and total checks performed. Colour-coded indicators show whether your connection is stable or frequently changing.
Private & Local-First Storage
All IP history is stored exclusively in your browser's localStorage - never uploaded to any server. Your IP addresses remain private and under your control. Clear your history at any time with a single click. No signup, no accounts, no tracking.
Common Use Cases for My IP History
VPN Connection Monitoring
Track how your public IP changes when connecting and disconnecting from VPN services. Use My IP History to verify that your VPN is correctly masking your real IP address and to detect any IP leaks that could expose your true location.
ISP Stability Analysis
Monitor how often your ISP changes your public IP address. Frequent IP changes can affect remote access, server hosting, and online gaming sessions. Track your IP change frequency over days and weeks to understand your ISP's DHCP lease renewal behaviour.
Network Configuration Testing
When configuring port forwarding, dynamic DNS, or remote access solutions, use My IP History to verify that your public IP changes match expected behaviour. Confirm that static IP assignments from your ISP remain stable over time.
Troubleshooting Connection Issues
When experiencing intermittent connectivity problems, track your IP changes to correlate with outages. An unexpected IP change might indicate a modem reboot, ISP-side issues, or problems with your network equipment that require attention.
Learning About IP Addressing
Students and networking enthusiasts can use My IP History to learn about public versus private IP addresses, DHCP lease cycles, and how ISPs manage their IP address pools. See real-world IP assignment patterns in action.
Mobile & Hotspot Tracking
Track IP changes when switching between mobile data, WiFi hotspots, and home networks. Understand how your public IP changes as you move between different network connections on your laptop, tablet, or smartphone.
Understanding My IP History
What is a Public IP Address?
A public IP address is a globally unique identifier assigned to your internet connection by your Internet Service Provider (ISP). It allows your device to communicate with other devices and servers on the internet. Unlike private IP addresses (used within your local network), your public IP is visible to every website and service you connect to. Public IPs can be static (permanently assigned) or dynamic (periodically changed by your ISP). My IP History helps you track changes to your dynamic public IP address over time.
How My IP History Works
- Fetch IP: When you click "Check Now", your browser sends a request to the ipify.org API, which returns your current public IP address. This is the same API used by many popular what-is-my-IP services.
- Record & Compare: The tool compares the fetched IP with your last recorded IP. If the IP has changed or if it has been more than an hour since your last check, a new entry is added to your history with the current timestamp.
- Store & Display: Your IP history is saved to your browser's localStorage. The timeline view shows every unique IP you've had, when each was first detected, and highlights your current IP. Statistics track total IP changes, days monitored, and change frequency.
What Determines IP Change Frequency?
- ISP DHCP Lease Time: Most ISPs use dynamic IP assignment via DHCP. The lease time (typically 24 hours to 7 days) determines how often your IP might change. When the lease expires, your ISP may assign a new IP.
- Modem/Router Restart: Rebooting your modem or router often triggers a new DHCP lease request, which can result in a different public IP being assigned by your ISP.
- VPN & Proxy Usage: Connecting to a VPN or proxy server changes your public IP to that of the VPN server. Disconnecting restores your original IP. Frequent VPN switching will result in many IP changes.
- Network Switching: Moving between different networks (home WiFi, mobile data, office network, public hotspots) changes your public IP since each network has its own ISP-assigned IP address.
Privacy & Data Storage
All IP history data is stored exclusively in your browser's localStorage - a local storage mechanism that keeps data on your device. No IP addresses, timestamps, or any other data are ever sent to our servers. The ipify.org API receives a request directly from your browser to look up your public IP, but this is a standard DNS-level request that reveals only the information necessary to return your IP address. You can clear all stored history at any time by clicking the "Clear History" button. The tool requires no signup, no account, and no API keys.

Frequently Asked Questions About My IP History
A public IP address is a globally unique identifier assigned to your internet connection by your ISP. It allows devices on the internet to find and communicate with your network. Unlike private IP addresses (like 192.168.x.x) used inside your home network, your public IP is visible to every website and online service you visit.
Most ISPs use dynamic IP addressing through DHCP, which means your public IP can change periodically. Common reasons for IP changes include: DHCP lease expiry (typically every 24 hours to 7 days), modem or router restarts, connecting or disconnecting from a VPN, switching between different networks (home, mobile data, public WiFi), or your ISP reallocating their IP address pool.
When you click "Check Now", the tool fetches your current public IP from the ipify.org API and compares it with your last recorded IP. If the IP has changed or if more than an hour has passed since your last check, a new entry is added to your history. All data is stored locally in your browser using localStorage - nothing is sent to our servers.
All your IP history is stored exclusively in your browser's localStorage on your own device. No IP addresses, timestamps, or any other data are ever transmitted to or stored on our servers. The API request to ipify.org goes directly from your browser. You can clear all stored data at any time with the "Clear History" button. No signup, no account, and no tracking required.
The change frequency shows how often your public IP typically changes. A low frequency (an IP lasting days or weeks) suggests a stable ISP connection with long DHCP lease times. A high frequency (changing multiple times per day) might indicate VPN usage, frequent network switching, or a short DHCP lease from your ISP. This information is useful for diagnosing connectivity issues and understanding your network setup.
Each device has its own public IP (unless they share the same internet connection through a router with NAT). Since the tool stores data in your browser's localStorage, each device and browser you use will have its own independent history. There is no cross-device sync since all data is stored locally and never uploaded to any server.
Clearing your browser's site data, cookies, or localStorage will delete all stored IP history for this tool. The history is only stored locally in your browser - there is no server-side backup. After clearing, the tool will start fresh with no history the next time you use it.
Yes, the My IP History tool is completely free forever. All IP lookups are made using the free ipify.org API, and all history storage happens locally in your browser. There are no usage limits, no signup requirements, no API keys needed, and no hidden costs. Use it as much as you like.
